Description
Technical field
The utility model belongs to mining equipment technical field, especially a kind of shell structure of Portable Methane Detection Alarm.
Background technology
In prior art, middle and small scale coal mine falls behind due to equipment, does not have perfect detection alarm means, when the ventilation of mine is not up to standard, is easy to produce gas exceeding limit, causes security incident.Therefore the most basic demand that underground ventilating situation is coal mine operation is detected.
And existing have the analogous instrument detecting underground ventilating status function not only volume be large, power consumption is large, internal memory is little, and certainty of measurement is low, and measurement means is single.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind of shell structure of Portable Methane Detection Alarm.
The purpose of this utility model solves by the following technical programs:
The shell structure of this Portable Methane Detection Alarm, comprise the outer cover body be made up of upper casing and lower casing, the upper end of described outer cover body is provided with valve, buzzer window and alarm lamp perforate is provided with on the top of the front panel of outer cover body, the middle part of outer cover body is provided with transom, the bottom of outer cover body is provided with facial mask; The back of outer cover body is provided with wireless charging module.
Fixed by valve seat between above-mentioned valve and outer cover body.
Further, facial mask is provided with circular switch key hole.
Above-mentioned upper casing and lower casing are outer cover body by the cross recessed countersunk head sscrew split that interfixes.
Further, lower casing internal fixtion is provided with battery pack, described battery pack is connected with wireless charging module.
Further, at the medial surface of described upper casing, circular switch key hole site is provided with keypad.
The utility model has following beneficial effect:
The shell structure of Portable Methane Detection Alarm of the present utility model adopts wireless charging module, can carry out wireless charging, and the female type charging avoided produces electric spark on plug, thus avoids dangerous generation; Further, the utility model structure is simple, easy to carry.
